I would expect that your unique rail system would have a problem with advancing to a consistent position, but clearly you have everything well under control.

I will guess that the 2nd insect is a kind of rove beetle. Although there is some diversity in their form and size, a similar one looks like this:

Cause i prefer continuous lighting rather than flash. Led lighting is not as strong as flash lighting. So, if you want to get enough exposure on your photo than you should keep open your shutter how much you need.

I had never heard of the use of "Bridge-Girder elastomeric bearing plates" before. In your opinion how good are they at minimizing vibrations?

Hate to continue on about this, and it is a small matter but i really think this is a rove beetle. There are 1000's of species, diverse in size and color and proportion. Look at the dorsal side, and I bet you will see the front wings are modified into short elytra._________________Mark Sturtevant
